In Sustainable Futures this term, students have been focusing on current issues impacting the Great Barrier Reef, including climate change, land-based run-off and ocean acidification. To deepen their understanding of the latter, students explored stoichiometry, and got hands-on in the lab in a titration practical. They also demonstrated their learning of issues affecting the reef through a discussion forum, in which they were asked to voice their thoughts on a series of pre-disclosed and impromptu questions.
